Abstract A volume estimation system based on Schumacher's total volume equation is developed for four commercially important northern hardwood species in Upper Michigan: sugar maple, red maple, yellow birch, and aspen. Given diameter at breast height and a measure of height, then total tree volume, volume to any height or upper stem diameter limit, and upper stem diameter at any height (for determining product class) can be estimated. Coefficients are given for estimating diameter or volumes either inside or outside bark as are examples illustrating the techniques and potential uses of the volume estimation system. North. J. Appl.

Abstract Planting of northern hardwood species interests forest landowners and managers who wish to continue growing pure or nearly pure stands of high-value species, enhance old-field conversion to preferred species, or reforest areas where natural regeneration has failed. Little data on planted hardwoods can be found, however. This paper reports on 22 years of growth of a northern hardwood plantation established in 1961 containing red maple, black cherry, sugar maple, and white ash. The data show that plantings of these species can succeed on good sites with weed control over the first few years, protection from animal predators, and close initial spacing. North. J. Appl.

Selection Harvesting

Abstract The natural regeneration that develops following the shelterwood and selection harvesting of northern hardwood stands across the Northeast is often plagued by an overabundance of American beech infected with beech bark disease. This regenerating beech typically dominates and interferes with the regeneration of more desired hardwood species (sugar maple, yellow birch, and red maple), lowering the productivity and value of future stands. We tested factorial combinations of glyphosate herbicide (Accord Concentrate) rate and surfactant (Entrée 5735) concentration to identify an optimal treatment that would maximize beech control while minimizing sugar maple injury. Third-year posttreatment results revealed that glyphosate rate was a more important factor than surfactant concentration in reducing beech abundance and preserving sugar maple. The optimal treatment (0.56‐1.12 kg/ha of glyphosate plus 0.25‐0.5% surfactant) selectively removed 60‐80% of beech stems, whereas sugar maple control was less than 20%. The five dominant hardwood species differed substantially in their susceptibility to the treatments in the following decreasing order: beech > striped maple > yellow birch > red maple > sugar maple. Similar results produced using a backpack mistblower suggested transferability of treatment effects to operational applications using a tractor-mounted mistblower. Our findings indicate that this relatively low-cost and effective treatment can substantially improve the understory composition of northern hardwood stands.

Mature Stands

Trends in gap dynamics among pole, mature, and old-growth northern hardwood stands were investigated on eight sites in the Porcupine Mountains of western upper Michigan. Recent gaps (created between 1981 and 1992) were identified using permanent plot records of tree mortality, while older gaps (1940–1981) were identified using stand reconstruction techniques. Although canopy gaps were somewhat more numerous in pole and mature stands, gaps were <25% as large as those in old-growth stands because of smaller gap-maker size, and the proportion of stand area turned over in gaps was only about half as large. Gap makers in younger stands generally had mean relative diameters (ratio of gap-maker DBH to mean DBH of canopy trees) <1.0 and were disproportionately from minor species such as eastern hophornbeam (Ostryavirginiana (Mill.) K. Koch). Gap makers in old-growth stands had mean relative diameters >1.5 and were predominantly from the dominant canopy species. Even in old-growth forests, most gaps were small (mean 44 m2) and created by single trees. Based on the identity of the tallest gap tree in each gap, nearly all shade-tolerant and midtolerant species have been successful in capturing gaps, but gap capture rates for some species were significantly different from their relative density in the upper canopy. The tallest gap trees of shade-tolerant species were often formerly overtopped trees, averaging more than 60% of the mean canopy height and having mean ages of 65–149 years. Canopy turnover times, based on gap formation rates over a 50-year period, were estimated to average 128 years for old-growth stands dominated by sugar maple (Acersaccharum Marsh.) and 192 years for old-growth stands dominated by hemlock (Tsugacanadensis (L.) Carrière). While these estimates of turnover time are substantially shorter than maximum tree ages observed on these sites, they agree closely with independent data on mean canopy residence time for trees that die at the average gap-maker size of 51 cm DBH. The data support previous hypothetical explanations of the apparent discrepancy between canopy turnover times of <130 years for hardwood species and the frequent occurrence of trees exceeding 250 years of age.

Chondrostereum Purpureum

Abstract Cultures of the fungus Chondrostereum purpureum (Fr.)Pouzar were applied to cut surfaces of hardwood stumps immediately after the trees were felled in late spring and summer and the stumps monitored for fungus infection and adventitious sprouting during the ensuing 2 years. Hardwood species inoculated were red maple, sugar maple, yellow birch, paper birch, pin cherry, trembling aspen, and beech. The fungus was applied as wheat bran cultures in a mineral oil slurry or by inverting petri dish cultures on the stump. All treatments resulted in development of sporophores of the fungus on the stump within 2 years and a concomitant reduction, as compared to the uninoculated controls, of the number of stump sprouts. The speed of stump invasion by the fungus and reduction of sprouting varied both among and within species. The feasibility of using this fungus as a biological control of regrowth after stand cleaning is discussed. North. J. Appl. For. 7(1):17-19, March 1990.

Abstract Eleven hardwood species were treated with seven herbicides during the spring, summer, fall, and winter seasons using a hypo-hatchet injector. Late spring to fall injections were most effective and winter injections least effective. Early spring injection tended to allow revegetation by outgrowth of lateral buds. Most of the herbicides were effective at the tested concentrations with injections of 1-2 ml/2.5 cm of stem diameter, with the best results from DOWCO 233, Krenite, Tordon 101-R and 2,4-D amine, respectively. Overall control ranged from 81 to 96 percent, depending on herbicide treatment. Multiple clumps of red maple stems were not well controlled by injecting just one stem.

And Storage

The species, quantities, and germination of tree seed stored in the forest floor beneath five northern hardwood stands in Pennsylvania were determined by counting seed found in blocks of forest floor material and running germination tests on them, by burying seed in soil organic layers and observing germination and storage, and by sowing seed on natural seedbeds and observing germination over several years. Quantities of seed in excess of 1 million per acre (2.5 million per hectare) were found to be common, the number of seed of a particular species depending on the number of seed-bearing trees of that species in the overstory and on the length of time seed of that species will remain viable in the forest floor. Sugar maple, eastern hemlock, and American beech normally germinate the year after seed dispersal and do not remain viable in the forest floor. Black cherry, white ash, yellow poplar, red maple, and birch normally germinate over a period of several years after dispersal; and storage in the forest floor for 2 to 5 years is common. Pin cherry seed remain viable in the forest floor for long periods, and large quantities of seed may still be present 30 years or more after pin cherry trees have died out of the overstory.

Volume Equations

A simple system for the estimation of stem volume is presented based on the compatible stem profile and volume equations. This system can directly predict the stem volume above breast height from measurements of stem diameter at breast height and at an another point along the upper stem, and does not require any sample data for determining a parameter of volume equation. In comparison with the prediction accuracy of existing volume equations from the literature, using data from Cryptomeriajaponica D. Don, Chamaecyparisobtsusa Endl., and Pseudotsugamenziesii (Mirb.) Franco, this system has the advantage of reducing prediction error.

A volume estimation system giving the stem profile (upper stem diameter outside bark), total tree volume, and merchantable volume to a height or diameter limit is developed based on a simple, variable form stem taper curve. The stem taper curve is defined by coefficient values indicating conic and parabolic tree forms. For a given height, small diameter trees are assigned parabolic forms and large diameter trees are assigned conic forms. A tree's position in the tree form continuum is defined by its total height to diameter at breast height ratio. Performance of the volume estimation system is evaluated using stem analysis information on red pine, jack pine, and white spruce from the upper Great Lakes Region.

Abstract Sugar maples (Acer saccharum Marsh) ≥ 2.0 in. dbh were evaluated for incidence of annual canker caused by Fusarium spp. A total of 1,880 trees were evaluated from 73 plots located on 635 ac of privately owned northern hardwood forest in north central Vermont. About 12% of the trees were dead and one-fourth of both living and dead trees had annual canker. A logistic regression model was used to assess the role of soil-site characteristics related to the incidence of annual cankering. Probability estimates from the estimated regression equation were used to generate a map of annual canker risk. The generality of the results obtained here are untested and need to be applied to a more extensive area for validation. However, the technique for forest disease risk assessment could have wide application. We found annual canker was more common on sites that maintained a high number of stems per acre, on sites that were shallow to bedrock, and on sites that were dominated by sugar maple. We believe these findings suggest that sites that have shallow soils that include sugar maple probably should not be managed to encourage sugar maple. Sugar maple probably should be managed in stands that contain ample stocking of other northern hardwood species, and cultural practices that encourage maple over other species probably should be avoided.
